We do not use the cloud. We operate (24/7) facilities in remote locations where we do not have super reliable internet connection (we do have redundant links including three different fibres on distinct paths plus radio links but still). For this reason alone nothing critical can be in the cloud. In our experience, however, cloud offerings are not that cheap compared to purchasing and operating your own machines. Besides, one still needs sysadmins even when operating infrastructure in the cloud.
